375815 divided by 17 
The aim is to understand the frequency of 17 in 375815.

Step 1:
17 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 17

On to step 2:
The number 17 fits into 37 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 34 from 37 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 17

On to step 3:
If we divide 35 by 17, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 34 from 35 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 17

Step 4:
17 can be fit into 18 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
If we take 17 away from 18, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 17

Advancing to step 5:
The number 17 fits into 11 0 times, leaving a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 2210.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 17

Moving on to step 6:
When dividing 115 by 17, we get 6 with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 22106.0
Subtract 102 from 115 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
17 can be fit into 130 7 times, resulting in a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 22106.7
If we subtract 119 from 130, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
110 divided by 17 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 22106.76
Subtracting 102 from 110 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 17 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 22106.764
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
17 goes into 120 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 22106.7647
If we subtract 119 from 120, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
10 divided by 17 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 22106.7647
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
100 divided by 17 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 22106.764705
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 22106.7647058
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
17 can be fit into 140 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 22106.76470588
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 22106.76470588, with a leftover of 4e-09.
